Abstract

A flame arrester includes a flame arrester housing that has a fluid channel defined therein and an inlet and an outlet which are communicated with the fluid channel. The fluid channel is internally provided with a flame arresting unit for preventing flame propagation One side of the flame arresting unit is provided with a deformation unit configured to deform when the internal temperature of the fluid channel reaches a preset temperature to reduce the flow area of the fluid channel towards the outlet. The deformation unit is provided on one side of the flame arresting unit, and when continuous combustion is formed at the flame arresting unit, the deformation unit deforms to reduce the flow area of the fluid channel on the surface of the flame arresting unit to increase a gas flow rate to move the flame is away from the surface of the flame arresting unit.
